一、引言 Likert量表(Likert scale)又称总加量表,由美国社会心理学家R.A.Likert于1932年在原有的总加量表基础上改进而成,并因此而得名。这种量表一般由一组与研究主题相关的陈述以及其他辅助内容所组成。它是由设计人员在一定的理论框架的基础上,顺从调查目的和要求而构制出来的,用来探知受试者对某一事物或现象...

A very common question is whether it is legitimate to use Likert scale data in parametric statistical procedures that require interval data, such as Linear Regression, ANOVA, and Factor Analysis.
Step 5 – Make a Report on the Likert Scale Analysis Select the rangeB4:H4and copy it to the clipboard. Go to a new spreadsheet and right-click on the cell you want to start the report (we have selected cellB4here), then click onPaste Specialfrom the context menu. ...

1. There is a difference between a likert scale item (a single 1-7 scale, eg.) and a full likert scale , which is composed of multiple items. If it is a full likert scale, with a combination of multiple items, go ahead and treat it as numerical. ...
However, it is not interval data. You cannot say the distances between “strongly agree” and “agree” would be the same as “neutral” and “disagree,” for example. People tend to think there is a bigger difference between items at the extremes of the scale than in the middle (there ...
